Patent number: 10034672Abstract: Tools or other instruments can be used by a surgeon to complete an orthopedic procedure. One tool can include a resection tower and a valgus guide. The resection tower can include a cutting block and a dial coupled with the cutting block. The resection tower can be configured such that rotational movement of the dial, about an axis, effectuates movement of the cutting block along a plane substantially parallel with the axis. The dial, when rotated in a first direction, can move between a first position, which corresponds to a minimum cutting depth of the cutting block, and a second position, which corresponds to a maximum cutting depth of the cutting block. The valgus guide can be coupled with the resection tower and includes a rotatable member. The rotatable member can include an angular surface with one or more variable depth splines providing varus/valgus angle adjustment of the cutting block.Type: GrantFiled: November 5, 2015Date of Patent: July 31, 2018Assignee: Zimmer, Inc.Inventors: Nolan C.

Patent number: 10022168Abstract: Embodiments provide a method and device for plate osteosynthesis of a bone fracture that allows angle-stable fixation of the bone fracture, while permitting elastic axial motion at the fracture site in a controlled, symmetric manner to stimulate fracture healing. Embodiments pertain to a bone plate having an outer surface and a bone-facing surface. The bone plate incorporating internal sliding elements containing a threaded receiving hole for bone screws that have a correspondingly threaded screw head. The sliding elements undergo controlled displacement parallel to the longitudinal axis of the plate but are substantially constrained against displacement perpendicular to the longitudinal axis of the plate. The bone screws with threaded heads may be rigidly fixed to the threaded receiving holes in the sliding elements without compressing the bone plate onto the hone surface. Sliding elements are elastically suspended inside the bone plate and undergo dynamic motion.Type: GrantFiled: June 7, 2017Date of Patent: July 17, 2018Assignee: Zimmer, Inc.Inventors: Michael Bottlang, Steven M.
